A year after release, Apple just announced its first update to the 12" MacBook with Retina Display. It's sort of a baby update, so we decided to match it with a baby teardown. Besides a faster processor and zippier flash memory, what changed? There's only one way to know: crack it open and spill its secrets. Join us for a mini-teardown of the Retina MacBook 2016.

If you weren't put off by the Pentalobes on the lower case, then a tri-wing probably won't slow you down much—but hey, we'll take what we can get!

Thankfully, all the other internal screws remain standard Phillips and Torx screws.

However, another surprise awaits at the hinge screws, whose Torx heads are filled with some sort of substance that disintegrates when you insert a screwdriver. Are you sealing our MacBook with tamper-evident screws, Apple?

The battery's form factor seems 100% identical to the multi-lobed cell we found in the 2015 Macbook.

And yet somehow, Apple managed to squeeze in a 4% capacity increase from the 7.55 V, 39.71 Wh battery in last year's model. Apple claims this new 7.56 V, 41.41 Wh Li-ion power source should provide up to 11 hours of iTunes movie playback.

We're guessing this capacity increase is owed to improved battery chemistry (though it's also possible that Apple's engineers have shaved away just enough material from the lower case to allow for a thicker battery).

Unfortunately, they did not squeeze in any of those nifty adhesive pull tabs we've seen in Apple'siDevices.

Yes. Apple designed SSD controller is next to the NAND flash chip as Step 7 shown. F4432ACPE-GD-F chip is next to Toshiba NAND Flash chip. SSD controller needs memory. In 2015 model, Apple uses PoP package to put it upon the SSD controller.
